Lack of production from the tight end position continues to be a problem for the Ravens.

Joe Flacco completed 22 passes Sunday, but only two of them went to tight ends. Ed Dickson started the game by dropping the only pass thrown to him. Billy Bajema had one catch for 18 yards. Dallas Clark had one catch for eight yards.

Not good enough said Ravens coach John Harbaugh.

“Those guys need to be a big part of what we are doing,” Harbaugh said Monday. “They’re fully capable of making catches. Ed should be a big-play guy up the seam, over routes, all those kind of things. We need to get him going. Billy made the catch on the naked on top of the linebackers, which was big for us. People consider Billy to be a blocker, which he does a great job of. But for him to able to get downfield and make some plays like that is important.

“Dallas had a big third-down conversion. Those guys have to be a bigger part of what we’re doing.”

So many NFL teams are using dynamic tight ends as a major part of their offense. The Ravens will be at a disadvantage if their output from that position does not improve.

“It’s such a valuable weapon to have,” Harbaugh said. “That’s something we think we should have as well going forward the rest of the year. We have the guys to do it. It seems like everybody’s got a tight end that can make plays. Those guys are big receiving threats, they can run. It’s probably the latest evolution in this league. There’s always been great tight ends. But I don’t think everybody had one back then.”

Losing tight end Dennis Pitta (hip surgery) during training camp remains a void the Ravens have yet to fill. Harbaugh has let it be known that he wants more from the tight ends that are still healthy.
